Hanahan capped its homecoming celebration with a A 55-21 victory over Hilton Head Island on Friday at Wiley Knight Stadium to clinch the Region 8-AAA championship Friday night.
The title is the second in as many seasons for the Hawks and secures homefield advantage through at least the first two rounds of the playoffs, which begin Nov. 8.
The Seahawks (7-2, 2-2) will face Berkeley next. The winner would finish third and avoid visiting a top seed in the first round of the Class 3-A playoffs.
Hilton Head took a 7-0 lead in the first quarter on Chase Rinehart's 1-yard touchdown run. The score came after the Seahawks' Jestin Morrow recorded an interception off the Hawks' Mason Schwerzler.
But Hanahan (9-0, 4-0) scored seven touchdowns, including four by senior running back Quan Wade, before the Seahawks would score again.
Freshman Tyler Hamilton was the Seahawks' workhorse, sandwiching scoring runs of 55 and 3 yards between two Hawks touchdowns late in the fourth quarter. Hamilton rushed for 171 yards on 30 carries.
A trio of injuries challenged the Seahawks even before stepping onto the field. Hilton Head was forced to play without quarterback Ben Oliff (leg), receiver Ja'Carri Aiken (concussion) and running back Khalil Lewis (high ankle sprain).
Hilton Head receiver Aaron Frazier came up short in his quest to become the Seahawks' all-time leading receiver. He needed 49 yards but gained just 32 on three receptions.
